R plication filed SeptemberlO, 1906. Serial No. 333,872.

To all whom it may concern: 1 l I 'Be it known-that I, ERAXK M. DAVIS, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invent- 'ed new and useful Improvements in Lubricaters, of which the following is a descrip-, tion, reference being had to the accompany ing drawings, which are a part of this specification.

This invention relates to lubricators and especially to lubricators for feeding lubricant in measured quantities and during the operation 'of the lubricated mechanism only.

The .invention is particularly adapted for use with explosive engines of the 1n0tor-vehicle type.- I mAn' object oh the invention is to so design the struclilreglfg ch a lubricator as to embody essentiaUparts of an existing type of engine construction and thereby become an intimate member of the engine construction. Another object of the invention is to pro vide a novel means for feeding and measuring liquid in a lubricator or the like.

Another object of thisinvention is to perfect details of construction of such devices.

With the above and other objects in view the invention consists'in the;(levice herein described, its parts and col lnbinations of parts and all equivalents. 1

ing for the cam shaft 8 are completed by the bearing sections 9, carried at opposite ends of a lubricator casing 10,

cover for the open upper end of.the e1 The lu'bricator casing 10 is in the nature of a rectangular which serves as a iglne lubricant receptacle ing a tight closure therefor and securedth'ereto' in any desirable site side walls of the l date suitable connectin for passing through ope nec ting said lubricator manner. ubricator 'lhc oppo casing 11) inwardly g bolts, not shown, mngs 13 in the base ofthe lubricator casing and securely concasin with the engine casing. The bottom of the reservoir portion of the lubru-ator casing is so shaped as to form a gear casing 1-1 at one end of the lubricator casing, within which a gcar wheel on the cam shaft 8 is housed, said gear'whc'el constitutlng one member of the means for gearing the cam shaft 8 with the crank shaft 7 and being omitted from the drawings.

it will be understood is adaptcd to perform tl operating the valvesof the cams and connect-i0 been shown.

A beveled pinion 15 meshes with a similar I the lower end of a vert passes upwardly throng that the cam shaft 8 1c usual functions of the engine, though ns thereof have not on the cam shaft 8 )inion .16 carried on ical shaft 17, which h an upright rib or projection 18 formed in the interior of the reservoir portion of th e lubricator casing.

The rib 18 is preferablyintegral with the end whereby the entrance of shaft 17 to the in te' rior of the oil reseri oir is accomplished without providing a passage through which oil might discharge.

v The upper end of the vertical shaft17 carries a worm 19 hearing on the upper end of-the 'rib 18.

lug 20 projects fro in the inwardly ex- 'end of a horizontal shaft 21, whose other end is journaled in a bushing 22 which is located in a hollow boss 23 on a reservoir with its opening said end wall so that t n end wall'of the oil passing tl'irough he s-iaft 21 may be passed thcrethrongh from the outside when assemblin theparts. Oll througi the bushin shape inclosing the entl There is no outlet for 23, as it is of a cupof shaft 21. At one and bottom-walls of the reservoir as shown,

end the shat t 21 has a worm wheel 24 secured thereto, which meshes with the worm 19 before mentioned, and bears upon the end of the hollow boss 23. At its other end said shall 2! has secured to it a worm 25 which. bears upon the bearing lug 20 before men tioned.

At about the central portion of the oil reserroir a vertical shaft 26 is journaled, with its upper end :titting in a depending socket bearing 27 on the cover 1], and its lower end seated in an upstanding socket bearing 28 in the bottom of the oil reservoir. Near its upper end the shall t 26 has secured to it a worm wheel 29 meshing with the worm 25, while near its lower end it has secured to it an er: centric disk 30, which bears upon and rides between a pair of upwardly extending parallel bearing flanges 31 on a yoke or slide member 32. 'lhe ilat enlarged head of the yoke or slide 32 rides upon the 11 )per surface of the socket bearing .28, beneath the eccentric 3t), and has a longitudinal slot 33 through which shaft 26 passes, forming a guide for said slide during its movements. the ilat head ortion, the slide or yoke 32 has a slotted or ifurcated guide extension 34, which rests upon a lug 35 in the bottom of the oil reservoir. There is a uide screw 36 threaded in said lug with a rol er or sleeve 37 mounted thereon and riding in the slot or bifurcation of said guide extension 34, to freely .erinit oi longitudinal movement of the slice or yoke but prevent its displacement. This guiding engagement oil the slide or yoke, coi'iperating with theengagement of the longitudinal slot 30 with shaft 26, )revents said slide or yoke moving out 0' its proper alinement while the rotation of the eccentric 30 reciprocatesit by riding between and bearing upon the transverse parallel upstanding flanges 31. The slide oryoke 32 has opposite side extensions'or enga ing arms 38 on its flattened head ortion w ich are let into recesses formed int eu per parts of cylindricalrods 39, which are on itndinally slidable, sons to move with sail slide or yoke member..

. 1 On both sides of the reservoir, the cylindrical rods 39 and their associated parts are identical in construction, and therefore it will be sufficient to describe such mechanism on one side of the oil reservoironly. A- pair of chambers 40 are formed on the bottom of the oil reservoir, one on each side of thecham nel or depression 12, 'anduhave their outer ends 5 aled by means of washers 41 carrying oil feed tubes 42 of brass or other flexible material leading therefrom. The washers are seated upon shoulders in the bore of the opening of the chambers and held in osition by means otscrew plugs 43 threaded in said here through the side of the oil reservoir. The screw lugs 43 are hollow to near their hearing ems, to enable the feed tubes 42 to Beyond by the nut 47.

be bent as shown in Fig. 2, without having a sharp bend which might injure or restrict them and interfere with the )assage oi? lubrirant theretln-ough. The ends of the rods 3t} pass entirely through both opposite walls oi the chambers 40 with close working :[it therein, and have reduced end extensions ht forming shoulders 1- Sleeves lfiareinoimted to slide on said end extensions between.

the shoulders 45 and stop nuts 47, which are 7 adjustably threaded on the extremities of said end extensions. The adjustment of these nuts serves to vary thefplay or longitudinal sliding movement of the sleeves 46 011 the and extensions 44. The sleeves 46, being of the same diameter asthe cylindrical rod. 39, are adapted to follow it through the walls of the chambers 40, and suitable men [is are provided. for detaining them and causing them to slide upon 'the end extensions -14 whenever the direction of movement of said". rod 39 is changed/so as to re uire them to be engaged alternately by the ioulders 45 and the nuts 47, to be moved. thereby and. overcome the effect of said means. As here shown the means for retarding the inovement of the sleeves 46 comprise s Jringa 48, (shown in Fig. 3), secured to the bottom of the oil reservoir and liltlSSlllg upwardly against said sleeves. The frictional engagement between the retarding springs db and the sleeves 46 holds them still, at the beginning of the stroke in each direction of the rod 39, until the. play or lost motion oi said sleeves on the end extensions 44 of said rod is taken .up, thus alternately producing spaces between the sleeve and shoulder -15 and between the sleeve and the nut 47. During the stroke in one direction the rod 39 passes throu h both walls of the chamber 40 and its shou der 45 is carried a short distance beyond the farther ,wall'with the sleeve bearing thereon. At the beginning 01 the return stroke, the sleeve being held. stationary by its detaining spring 48, is leit by the shoulder 4,5 and is engaged at the other end The space thus formed be tween the sleeve and the'shoulder 45 is occu pied by lubricant contained in the reservoir,

and. as the rod 39 continues its movementfli and the sleeve 46 is drawn through the wall of the chamber 40, the lubricant contained in said space is carried into the interior of the outlet-chamber.

the sleeve 46 being again detained by its spring 48, the shoulder 451n'oves toward the end .of the sleeve, forcing the oil. out of the space therebetween and into thie chamber; until the engage and move on through the wall of t e. chamber to repeat the operation: just described. The amount ofoil fed to the interior of the chamber 40 by each rcciprocation of the rod 39 depends upon thesi'ze of thespace. left between the end of the slceirc we lit] When, however, the rod 39 begins its stroke in the other direction again, '1

engaging the notched edges thereof. .A conical strainer 52 of brass gauze or other The interior or the oil reservoir is vented b sheet metal surrounding the sleeve 46 and firmly sleeping it, with outwardly bent sepaof the chamber 401 respectively. The opera finore reduced speed by driving theavorm reservoir at the filling opening in thecov'er'l gear casing I1 4 in the bottom of the reservoir 7 to near ,the cover of said reservoir, and thus ,ing spring' for the sleeves-46 is shown. It

offthe lubricant into the spaces between the sleeves 46 and shoulders 45"for the lubricant tion of vertical shaft 17 by the inter-meshing and the shoulder 45, which may be varied by adjusting the position of nut 47, so that the su .iply of oil to theparts with which the oil tubes 42 connect may be increased or diminished to suit the requirements.

In order to facilitate the assembling of the parts, a 1.-'e1novable screw plug 49 is provided m ths endwall of the oil; reservoir, in,=aline nientiwith the rod 39, through the opening, for which'saidrod'with its parts may be passed. To facilitate the charging of thefecd tubes aneedlej valve 51, which normally locked osed by means of a-springvcatch 5.1 on the suitable material issuspended within the oil and a screw cap .53 tightly closes said openin means of a vent tube 54, which rises from the pressure which may be present in the engine casing will be transferred to the lubricator casing. so that the pumps will not have'to opcrate against great back pressure.

In Figsfi and 6 a modified form of detainconsists in a plit cylindrical shell 55 of spring rated fingers at its ends to bear against the end of thelubricato'r casing and the wall tion of this form of spring the same as the other and does not interfere with the passage is free to passbetwe en the fingers 56..

The operation of the rods 39 and their associated parts, in forcing or pumping oil-into the chambers 40, to be led therefromby the feed tubes 42 to the-cylinderand hearings or other parts of the engine with which the lubricator is connected, has been-fully set forth, ;andthe means for 'ng motionto the-rods 32) may. be traced as iollows: The rotation of 'the canr shaft 8 in the usual manner causes the rota beveled, pinions l5 and 16, and thereby turns the worm L9. The Worm. wheel-24 isturned at a reduced speed by the worm 19, and the WOllIll 25 on the same shaft therewith serves in turn torotate the vertical shaft 26 atla wheel 29 thereof. 'lhus the-eccentric 30 carried by the shaf t 26 is caused to rotate slowly and move 'over the'fiattenedhead porl ion of the slide 323, between the upstandiiw'llanges 31 thereof, and by engag ng thcs "flanges alternately with a cam action, the said slide is caused to reciprocate "regularly; being guided by its bearing on the sides of the shaft 26 and by the guide screw so, with its side arms 38 engaged with the rods ill) to give them the reciprocalion necessary, for sup )lying the oil as before slated.
